Abstract
Dielectric spectroscopy measurements of bulk and emulsified high-density amorphous ices (HDA) at 1.0 GPa were carried out to examine the effect of emulsion matrix on the dielectric spectra. The presence of emulsion matrix induces the shifts of the loss peak to higher frequency side. The degree of shift depends on the volume fraction of the emulsion matrix to HDA. This indicates that the relaxation time obtained from the dielectric spectra of emulsified HDA is underestimated than the true relaxation time of HDA. The results suggest that the emulsified sample is not appropriate for dielectric spectroscopy measurement in water polyamorphism study, although the emulsification is effective, for example, in avoiding water crystallization.
